are there expantion packs for sims3 on wii?

I have the Wii version as well but no, there are no expansion packs for any of the game consoles. However, different types of Sims are available. I got a PS3 last năm and I got Sims 3: Pets. It is actually the one I prefer to play.
But if bạn have an internet connection, bạn may be able to get on the Sims website which usually offers other stuff. Hope this helped :)
